RIVETING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 775,215, dated November15, 1904.

Serial No. 208,353. (No model.)

To (all 111/1 0111. if may concern:

Be it known that I, LYMAN G. GLAZIER, a citizen of the United States,residing at Philadelphia, county of Philadelphia, and State of 1Pennsylvania, have invented a certain new and useful Improvement inRiveting Machines, of which the following is a specification.

My invention relates to a new and useful improvement inriveting-machines, and has for its object to construct a powerrivetingmachine by which the rivets are fed automatically to themachine, said rivets being forced through the material to be riveted andturned all at one operation.

\Yith these ends in view this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claim.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, the constructionand operation will now be described in detail, referring to theaccompanying drawings, forming a part of this specification, in which---Figure l is a side elevation of my improved machine; Fig. 2. a sideelevation of the upper portion of the machine, a portion of the partsbeing shown in section; Fig. 3, a similar view to Fig. 2, showing themachine in the act of setting a rivet; Fig. 4, an elevation of one ofthe spring-jaws; Fig. 5, a vertical section through one of the rivets.

A represents the standard of the machine, which may be of any suitableshape or design.

B is a table upon which the riveting is done, a point B being formedwith the table in the center for spreading the rivets.

O is the vertical head of the machine, through which is adapted to slidethe tube D. Said tube has secured upon each side at its lower end twospring-jaws E, adapted to hold the rivet while the tube D is forceddownward to the material to be riveted.

F is a plunger adapted to slide vertically within the tube D, and theupper end of the plunger F extends above the upper end of the tube I),and coiled about this upper end of the plunger is a spring G, interposedbetween a collar upon the upper end of the plunger and the upper end ofthe tube.

H is a lever pivoted intermediate of its two ends to the standard. Oneend of the lever is connected to the upper end of the plunger F, and theother end of the lever is connected to a link I, extending downward to afootlever J, by which the machine is operated. J is a spring forreturning the foot-lever and other parts to their normal position. Thusit will be seen that if a rivet is held by the spring-jaws E and thefoot-lever depressed the tube I) will first travel downward until thespring-jaws come in contact with the material to be riveted. Then on acontinued motion of the lever H the plunger F will be forced downwardagainst the tension of the spring Gr, forcing the rivet into thematerial, spreading the spring-jaws, and as the hollow end of the rivetcomes over the point B upon the table B the rivet will be spread, asshown in Fig. 3. Then as the pressure is released from the foot-leverall the parts will return automatically to their normal position.

In order to feed the rivets automatically to the machine, I haveprovided a rivet-receptacle in the form of a tube K, which extendsdownward alongside of the head O, and the lower end of therivet-receptacle terminates in the horizontal guideway L, adapted toguide a plunger M, the rearward end of said plunger being connected toone end of a lever N, said lever being pivoted intermediate of its twoends to the standard and the upper end of the lever N being connected toa rod O, slidably mounted in the framework of the machine, the forwardend of said rod lying within the path of travel of a beveled projectionP, extending outward from the tube D through a slot P, formed in thehead.

Q is a spring tending to pull the plunger M rearward and force the rod Oforward. IVhen the plunger M is pulled rearward by the spring Q, theforward end of the plunger M lies rearward of the rivet-receptacle, sothat the lowermost rivet within said recept. cle may fall downward infront of the plunger. Then as the tube D travels upward and just beforeit has reached the limit of its movement the beveled lug P strikes therod- O and forces the same rearward, which through the lever N willforce the plunger M forward, and said plunger will carry the lowermostrivet through an opening R into the lower end of the tube D below theplunger F. Then upon the first movement of the tube D downward theplunger M will be withdrawn, which allows the rivet to drop downwardinto the spring-jaws, and the operation of riveting will be performed asbefore described.

Of course I do not wish to be limited to the exact construction hereshown, as slight modifications could be made without departing from thespirit of my invention.

Having thus fully described my invention, what I claim as new and usefulis In a device of the character described, a standard, a tube adapted toslide vertically within said standard, a plunger fitted to slide withinthe tube, aspring interposed between the tube and the plunger tending toforce the plunger upward relative to the tube, a footlever pivoted tothe standard, mechanism adapted to depress the plunger when thefootlever is depressed, a spring for raising the foot-lever whenpressure is released, two spring-jaws pivoted upon opposite sides of thelower end of the tube adapted to normally hold the rivet against its ownweight but adapted to spread under pressure to allow the rivet to passbetween the same, a table secured to the standard, a rivet-spreadingpoint secured in the center of the table, the lower end of the tubeprovided with an opening formed through the same, a verticalrivet-receptacle, ahoriZontally-sliding plunger at the lower end of therivet-receptacle, the forward end of said plunger adapted to lierearward of the lowermost rivet when said plunger is at its limit ofmovement in one direction, ,a horizontally-sliding rod mounted in theframework, a beveled lug formed with the tube adapted to force said rodrearward when the tube is raised, a lever connection between said rodand the horizontal plunger adapted to force said plunger forward tocarrya rivet through the opening into the tube when'the -rod is forcedrearward, and a spring for returning the feeding parts to their oppositeposition when the beveled lug is removed from in front of the rod, asspecified.

In testimony whereof I have hereunto affiXed my signature in thepresence of two subscribing witnesses.
